These are four different equation sorts for students to practice equality. There are four sorts for differentiation depending on the students you have. The first two sorts are solely addition, the third is mixed addition and subtraction, and the fourth is mixed addition and subtraction with more than two addends. I print these sorts on different colored sheets, laminate them, cut them, and place them in baggies so they can be used for an independent activity during math workshop. You could also have students cut them up, sort them, and glue them into their math journals.
